Hello!
First of all, forgive me for bad English.
When I starts new thread (pthread_create), system allocates some memory for it (for example, for thread's stack). I wonder when does it deallocate this memory? The problem is that I have a program which sometimes creates new threads and sometimes... (3 Replies)
Hi all,
I have a HP-UX Server with 4 gigabytes of physical RAM. When I use the 'Glance' utility to see what my memory utilization is, my memory usage shows up maxed out at 99%. I shut off all the known processes that I'm running on that box and the memory utilization is still at 78% (with Swap... (3 Replies)
Hi,
I am trying to process line by line of a file. But I should not be allocating static allocation for reading the contents of the file. The memory should be dynamically allocated. The confusion here is how do I determine the size of each line, put it into a buffer with the memory allocated... (11 Replies)
I have a program that will fetch some particular lines and store it in a buffer for further operations.The code which is given below works but with some errors.I couldn't trace out the error.Can anybody help on this plz??

I have a scenario like the client has to search for the active server.There will be many servers.But not all server are active.And at a time not more than one server will be active.
The client will be in active state always i.e, it should always search for an active server until it gets one.I... (1 Reply)
Hi everyone,
I'm not new to C programming, but I'm having question regarding the memory allocation of a pointer variable which, for instance, will be declared in main(), but its memory will be allocated in subroutine.
To clearify my question, I provide a small working example:

hi
in the following code, how the memory is allocated for a1 which holds the values of a2 after cpy function call.
#include <stdio.h>
#include <string.h>
void cpy(char* d, const char* s){
while(*d++=*s++);
}
main(){
char* a1;

Hello,
I am new to C++ programming, so I'm still getting a feel for things. I recently wrote a simple C++ program (to be used as a ROOT Macro) to conduct a statistical analysis of a varied version of the Monty Hall problem (code below). Basically, the programs runs a few simple calculations to... (7 Replies)

free_printf_comp
XPRINTF_COMP(3) BSD Library Functions Manual XPRINTF_COMP(3)NAME
free_printf_comp, new_printf_comp -- extensible printf compilation
SYNOPSIS
#include <printf.h>
void
free_printf_comp(printf_comp_t pc);
printf_comp_t
new_printf_comp(printf_domain_t restrict domain, locale_t restrict loc, const char * restrict fmt);
DESCRIPTION
To ameliorate some of the slowness caused by the extra overhead in extensible printf (see xprintf(5)), a compile/execute mechanism has been
created. The new_printf_comp() function compiles the given format string, along with a printf domain (see xprintf_domain(3)) and an extended
locale (see xlocale(3)), and returns a printf_comp_t structure. The domain may not be NULL, but the locale can be NULL, which means to use
the current locale, either the per-thread locale if it was set, or else the global locale. Because the printf_comp_t structure records the
domain and locale, care should be taken if either of these are changed.
Once a printf_comp_t structure is created, it can be passed to one of the extensible printf execution variants, described in xprintf_exec(3),
along with the necessary arguments. Creating the printf_comp_t structure needs to be done only once, but it can be passed to extensible
printf execution variants any number of times.
When the printf_comp_t structure is no longer needed, it should be passed to free_printf_comp() to release internal memory.
RETURN VALUES
The new_printf_comp() function returns the new structure, or NULL on error (usually NULL domain or out of memory condition).
